Re: Soviet Air force
 

Pokryshkin claimed almost all of his victories in the days of fierce fighting in the air, so considering overclaim, it is rather impossible to identify whom he shot down and if he shot down something indeed. Thus, for 21 september 1943 for three Rumanian Ju-88 losses, 8 Soviet claimers, excluding Pokryshkin.
BTW, Rechkalov did not claim Ju-88 on this date...
